Hey Fish,
In today’s society, it is difficult to be fully present and truly forget the past and the future. In fact, it might not be beneficial to completely ignore them, unless you decide to move into a cave up on a mountain and spend your life in meditation.

The fact that the past and future have to, inevitably, be acknowledged does not preclude mindfulness. You can still be mindful in your everyday life. Stay mindful as you put on your clothes, stay mindful as you do the dishes, stay mindful as you walk. If you are in a state of mindfulness, and are consequently calm and grounded, the decisions won’t feel like such burdens. While you are analyzing your prospects, stay mindful of your emotional reactions, and question yourself to see if you are just worrying, or if your process is productive.

There is a difference between planning and worrying, and as long as you don’t get stuck worrying you should be good to go.
Just keep experiencing every step of the way in your body, and you’ll have a better idea of what to do.

I hope this helps!

Warmly,
Katerina
